Relating to or containing andesite, a type of volcanic rock with a chemical composition between rhyolite and basalt.
Derived from andesite (named after the Andes Mountains where such rocks are common) plus the chemistry suffix -ic, indicating 'of or relating to.'
Andesite rocks are so common in volcanic zones that geologists use them as a signature—wherever you find lots of andesite, you're likely in an ancient or active volcanic region.
